had them by the dozen a few years back iirc. I know these are in the NL for sure.
Yes I can confirm that ! I saw them with my own eyes. It was my first visit there and I was still in my MAME-cab days, so I didn't quite understand the value of those babies. When we went over to pick up Ully's Night Driver I mentioned them to the seller and he told me they were NOS !!! For some reason they didn't comply to European electrical safety regulations and thus were never sold.Not sure if it's true, but tha's what he told me. I think there were at least 10 of them there (they were up in "stellingen" (is that scaffolds ?) all covered under plastic IIRC. Guy said he probably sold them for too little momey when I said they were quite valuable......
I think he said someone bought them all at once, but not sure.....and he didn't mention if it was a Dutch guy....strange that they didn't resurface....what does anyone want to do with 10 (or more) of them....
